Taxanaha Oksijiin Oksijiin
Hordhac: Warshad wax soo saar oo caan ah, waxaan ku takhasustay soo saarista alaabada tayo sare leh oo u adeegeysa baahiyaha warshadaha kala duwan. Taxanahayaga bumikada ah ee oksijiinta oksijiinta oksijiinta ah ee oksijiinta ah waxay heleysaa xallin dhameystiran oo loogu talagalay qaybinta hufan ee aaminka ah ee oksijiinta dareeraha ah. Sharraxaaddan wax soo saarku waxay bixin doontaa dulmar guud oo ku saabsan astaamaha ugu muhiimsan, faa'iidooyinka, iyo faahfaahinta farsamada ee taxanaha ah ee taxanaha ah ee oksijiinkeena oksijiinta ee oksijiinka ah, ka caawinta inaad sameyso go'aan la wargeliyey.
Muujinta alaabada:
- Qeybinta gaaska ee aan kala go 'lahayn
- Dheerinimo Sare ah
- Rakibaadda sahlan: Tuubooyinkayagu waxay muujinayaan qaabab rakibaadda-u-habboon,, waqtiga badbaadinta iyo dadaalka inta lagu gudajiro setup.
- Ikhtiyaaraadka ikhtiyaariga ah: Waxaan bixinaa cabbirro kala duwan iyo qaabeynta gudaha taxanahayaga bumikada ee oksijiinka ee oksijiinka ah, hubinta is-waafadahay shuruudahaaga gaarka ah.
- Xakamaynta Tayada Tooska ah
Faahfaahinta badeecada:
- Qaybinta gaaska ee aan kala go 'lahayn Tuubkeena, waxaad hubin kartaa in la maro si joogto ah oo aan kala go 'lahayn oo oksijiin dareere ah, oo yareynaysa xilliga firaaqada iyo kor u qaadista wax soo saarka.
- Waafajinimo sare iyo nabadgelyo sare: oo lagu dhisay waxyaabo waara, tuubooyinkeenu waxay awood u leeyihiin inay ka jees jeesaan heerkul xad dhaaf ah iyo cadaadis sareeya. Tani waxay ka dhigeysaa inay si aad ah ugu kalsoonaan karaan oo nabdoon in loo isticmaalo muddada-dheer. Intaa waxaa sii dheer, tuubooyinkayaga waxaa loogu talagalay nabadgelyada maskaxda, iyagoo yareynaya halista daadadku ama shilalka inta lagu gudajiro gaadiidka iyo qaybinta dareeraha dareeraha ah.
- Ku rakibida fudud iyo dayactirka: Taxanahayaga bunniska ah ee oksijiinka ah waxaa loogu talagalay rakibaadda fudud, waqtiga badbaadinta iyo dadaalka inta lagu gudajiro setup. Tuubooyinka waxaa lagu qalabeeyaa isku xirayaal-saaxiibtinimo-saaxiibtinimo, oo u oggolaanaya is dhexgalka degdegga ah ee bilaashka ah ee ku dhaca nidaamyadaada jira. Intaa waxaa sii dheer, tuubooyinkayagu waxay u baahan yihiin dayactir yar, yareynta carqaladeynta hawlgalka iyo hagaajinta wax soo saarka.
- Ikhtiyaaraadka ikhtiyaariga ah: Waxaan bixinaa cabirro kala duwan iyo qaabeynta gudaha taxanahayaga bumikada ah ee oksijiinka oksijiinka ah, hubinta is-waafaqaynta codsiyada kala duwan. Kooxdeena khubarada ah ayaa kaa caawin kara xulashada xulashooyinka ugu habboon ee ku saleysan shuruudahaaga gaarka ah.
Marka la soo koobo, taxanahayaga bukooyinka ah ee oksijiinka ah wuxuu keenaa xalal qaybinta hubaysan oo badbaado leh. Iyada oo la qaybiyay gaaska, cimri dherer sareeya, rakibaadda fudud iyo dayactirka, iyo ikhtiyaarada nashaadaadka, taxanaheena tuubkeenu wuxuu sifiican ugu adeegaa baahiyaha warshadaha kala duwan. Xulo taxanahayaga oksijiinkeena oksijiinka ah si kor loogu qaado nidaamkaaga qaybinta oksijiinta ee oksijiinta leh isku halaynta iyo hufnaanta la xoojiyay.

Vacuum-ka daboolan
Faakida faaruqa ah ee tuubada (tuubada viping), oo ah faafin kara tuubbada jaakada (tuubada vj), sida bedel wanaagsan oo lagu beddelo dahaarka tuubbada tuubbada caadiga ah. Marka la barbar dhigo dahabiga tuubada caadiga ah, qiimaha kuleylka kuleylka ee VIP waa kaliya 0.05 ~ 0.035 jeer ee dahabka tuubbooyinka caadiga ah. Si weyn u badbaadi tamar iyo qiimaha macaamiisha.
Taxanaha sheyga ee tuubbada tuubbada bannaanka lagu tuuro, vacuum tuubada jaakada, iyo kala-sooca ka-dhiska ah ee shirkadda hudheegga ah, oo dareere ah, oo ah hayo dareere ah, oo ah luuqado, iyo lng, taangiyadan. Dewos iyo sanduuqyada qabow ee iwm)
Saddex nooc oo isku xirka ah ee tuubada VI
Saddexda nooc ee isku xirnaanta halkan waxay quseysaa oo keliya jagooyinka isku xirka ee u dhexeeya tuubooyinka VI. Marka VI tuubbada ay ku xirayaan qalab, haanta keydka iyo wixii la mid ah, isku xirnaanta isku xirnaanta ayaa loo habeyn karaa iyadoo loo eegayo shuruudaha macaamiisha.
Si kor loogu qaado baahiyaha kaladuwan ee macaamiisha, faaruqa qashinka lagu xiray ayaa soo saaray saddex nooc oo isku xirnaan ah, oo ah noocyada isku xirka bayanet ee bayonet bayonet ee ku jira boobbooyinka iyo boorsada ku jirta baronet iyo bolts-ka iyo xilka isku xirka. Waxay leeyihiin faa iidooyin kala duwan waxayna ku habboon yihiin xaalado shaqo oo kala duwan.
